Product Description
Insulfoam® Commercial Wall Insulation consists of high-quality expanded polystyrene (EPS) panels designed for a wide range of wall applications—exterior sheathing, cavity fill, continuous insulation (CI), EIFS, interior walls, gable ends, and tongue-and-groove systems. The lightweight yet resilient boards offer stable R-value, moisture resistance, and recyclability, plus compatibility with wall assemblies requiring structural and thermal performance. The product is backed by a 20‑year R-value warranty.
Key Benefits
- Moisture Resistant: Closed-cell EPS, low absorption and quick drying—ideal for wall environments.
- Long-Term R-Value Stability: No thermal drift over time, with a full 20-year performance warranty.
- Dimensional Stability & Resilience: Excellent resistance to warping and compression, even in high-moisture conditions.
- Environmental & Code Advantages: 100% recyclable, contributes to LEED credits, no ozone-depleting blowing agents.
- Easy to Specify & Install: Available in 4′×4′ or 4′×8′ boards, up to 40″ thickness, with custom shapes and tongue-and-groove options.
